Marwan ibn al-Hakam ibn Abi al-As ibn Umayya, commonly known as Marwan I, was the fourth Umayyad caliph, ruling for less than a year in 684–685. He founded the Marwanid ruling house of the Umayyad dynasty, which replaced the Sufyanid house after its collapse in the Second Fitna and remained in power until 750.

The Umayyad Caliphate or Umayyad Empire was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty. Uthman ibn Affan, the third of the Rashidun caliphs, was also a member of the clan. The family established dynastic, hereditary rule with Mu'awiya I, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power eventually fell to Marwan I, from another branch of the clan. Syria remained the Umayyads' main power base thereafter, with Damascus as their capital.
Arab-Sasanian-style Umayyad coin minted under Mu'awiya I rule in Basra in 675/76 in the name of the Umayyad governor Ubayd Allah ibn Ziyad. The latter's governorship later spanned all of the eastern caliphate. His father Ziyad ibn Abihi was adopted as a half-brother by Mu'awiya I, who made him his practical viceroy over the eastern caliphate.
Abd al-Malik introduced an independent Islamic currency, the gold dinar, in 693, which originally depicted a human figure, likely the caliph, as shown in this coin minted in 695. In 697, the figural depictions were replaced solely by Qur'anic and other Islamic inscriptions
